Dt973H electric resilient metal sealing butterfly valve

Dt973H electric resilient metal sealing butterfly valve using “U” type stainless steel sealing ring, the ring contact with three-dimensional eccentric of butterfly board. Widely used in pipes of metallurgy、power、petroleum、chemical、air、gas, flammable gas that temperature≤550℃, for adjusting flow and cutting off fluid

1、 simple structure、impact、light weight、easy to install and uninstall、maintain

2、 using “U” type sealing ring, with good sealing even under high temperature、low temperature

3、 three-dimensional eccentric distance, through rigorous calculation, “U” type sealing ring and butterfly board with no friction, long using life

4、 sealing surface of butterfly board using Co-based cemented carbide, wear resistance of sealing surface, long using life

5、 special valve structure, “on-off” just need to rotate 90°of valve stem. Flexible operation、convenient、effort、not affected by media pressure, reliable sealing performance

6、 high temperature resistance、low temperature resistance、anti-corrosion
